Workspace
The exact size of the active area of a tablet (or screen in a graphic display) in width and height. In general, it is more of a reference than a practically significant parameter: when choosing a traditional graphics tablet, there is often enough information about the format (see above), and for displays, primarily the diagonal (see above) and aspect ratio (see below) are of practical importance . However, the exact dimensions can also be useful in fact: for example, you can determine the aspect ratio from them (for classic tablets, this parameter is often not indicated).
Size
Diagonal of the working area — the screen itself — in a graphic display (see "Type").
In general, the larger the diagonal, the more convenient the device is to use: a large working area covers a large area for drawing and at the same time allows you to work effectively with small details. On the other hand, this parameter directly affects the price, and the dimensions cannot be discounted: in some cases, there may simply be no room for a large device.
By the standards of graphic displays,
13.3" or less is considered small,
15.6" is considered medium, and many models have
larger screens. And it is customary to evaluate the size of traditional tablets by the format, and not by the diagonal.
Control keys
The number of control keys provided in the design of the tablet.
Each of these keys is responsible for a specific function, while the set of these functions can be configured: in some models they can be selected manually, in others the functionality of the keys changes automatically, depending on the currently active application. Anyway, additional keys allow the user to perform various actions without looking up from the tablet — this can be very convenient in the midst of the work process, when you don’t want to change the pen to the mouse again or reach for the keyboard. And the more control keys — so, respectively, more additional actions can be performed using the tablet. On the other hand, with relatively simple tasks, the abundance of additional buttons can hinder and confuse the user rather than help.
The most modest modern tablets provide
up to 5 control keys ; the most popular option is
from 6 to 10 keys, and in advanced models this number can reach
15 or even
more.
Card reader
The presence
of a slot for memory cards in the design of the tablet.
This function allows the device to work with removable media — actually memory cards; but the specific format of such work may be different, depending on the model. The most popular option is to use the tablet as an external drive: you can store working materials (projects, sketches, sketches, finished drawings) on a memory card and have access to them regardless of which computer the device is connected to. Such features will be especially useful for those who often have to move from place to place — for example, students who work both in the classroom and at home. At the same time, a memory card makes it easy to transfer data to tablet PCs, laptops and other devices that support such media (although in some cases an adapter may be required for this).
Connector on device
- microUSB. A smaller version of the USB connector designed for portable devices. Currently it is losing ground to the USB type C interface with a more convenient symmetrical contact group.
- miniUSB. Almost the same interface as described above, which differs only in the size and shape of the connector.
— USB A. Standard (full-size) USB connector used to connect the device to a computer and other external devices.
— USB C. A miniature version of the USB connector, gaining popularity and in the future capable of displacing microUSB. The interface has a high data transfer rate, and most importantly, it is symmetrical, so the plug can be connected to either side.
- Branded. A connection connector that does not belong to generally accepted standards and is used to a limited extent - in models of one or several manufacturers. However, due to general standardization, this option has practically disappeared from the scene.
Resolution
The number of horizontal and vertical pixels from which an image is formed on the graphic display screen (see “Type”). Higher resolution results in sharper, more detailed images for precise graphics work. However, high resolution affects the cost of the graphics display.
As for specific resolutions, models with
Full HD screens predominate in wide use. Less common are models with
2K or even
4K displays.
Panel type
The type of matrix installed in the screen of a graphic display or computer (see “Type”).
- IPS. The technology provides high quality color reproduction, good brightness and wide viewing angles. In addition, IPS screens are relatively inexpensive to produce, which is why they are widely used.
- H-IPS. A variation of the original IPS technology, designed to increase viewing angles and contrast while maintaining high-quality color reproduction. Used in professional graphics tablets.
— TFT. The simplest type of liquid crystal matrices used in color displays. Such panels provide relatively low, but generally sufficient image quality, and they are noticeably cheaper than more advanced technologies. The obvious disadvantages of TFT are very limited viewing angles.
Brightness
The maximum brightness in cd/m² that the device screen produces.
High brightness displays remain highly readable under intense ambient light, such as when the workplace is exposed to sunlight. A dull image on a graphics tablet screen can be “blown out” by such lighting. Note that a large margin for this parameter affects the cost and power consumption of the display.
Colour gamut (NTSC)
The range of colors that can be displayed on a graphics tablet screen. The parameter is indicated as a percentage relative to the coverage of the NTSC color space. The larger the color gamut, the wider the capabilities of the screen and the better the quality of its color rendition, which is extremely important when working with graphic materials.
NTSC is one of the first color models, launched in 1953 for color television. And it is still used to describe and compare matrices. The NTSC model covers a larger range of colors than the standard sRGB used in computer technology, so even a relatively small number of percentages corresponds to a fairly wide coverage. For example, a value of 72% or more according to NTSC is considered a decent indicator for use in design and graphics.
